Netero's scene is excellent, well most of his scenes are, I will dedicate something to it. The interesting thing is that it plays with the viewer at that moment I think almost all of us thought that Hisoka could kill Netero easily, the weird old man seemed harmless and I think Hisoka noticed that this old man was not normal because his aura never changed having him in front of him. In Machi's case, I think that the way to express attraction beyond the carnal is suffering.
